Davis-based Marrone Bio Innovations Inc., a provider of bio-based pest management and plant health products, says it has received U.S. Environmental Protection Agency approval of a product to combat invasive mussels in lakes, rivers and other waterways.
Marrone touts Zequanox as the industrys only selective and environmentally compatible molluscicide. With the new EPA approval, the company says Zequanox offers private waterfront owners and natural resource managers a way to control existing populations of mussels or reduce new infestations without environmentally harmful potash and copper-based products.
Zequanox, composed of dead cells derived from a naturally occurring soil microbe, controls mussels in all life stages, Marrone said.
Mussel populations are now prevalent in major waterways throughout the United States, including the Great Lakes region as well as in Mississippi, Arkansas, Tennessee and Colorado rivers, according to Marrone. Infestations can disrupt ecosystems and cause proliferation of toxic blue-green algae.
In August 2013, Marrone Bio completed the Sacramento regions first initial public stock offering since 2006, raising $57 million. Since then, it has focused on boosting revenue, building its financial standing and getting regulatory approvals of its products internationally.
